Interpretation Introduction

Interpretation: For the given structures the multiplicity of each signal to be identified.

Concept Introduction:

Multiplicity: The number of peaks on the each signal in NMR spectrum is defined as multiplicity; the multiplicity of each signal indicates the neighboring protons. It is generated by coupling of the subjected protons with the neighboring protons (both subjected and neighbor protons are to be chemically not equivalent) separated by either two or three sigma bonds.

Rule: Multiplicity of each signal is calculated using (n+1) rule only when the neighboring protons are chemically equivalent to each other.

(n+1)where n indicates number of neighboring protons
